Support frame molding plastic mold for metal tube connection

Abstract

The invention discloses a support frame molding plastic mold for metal tube connection. The molding plastic mold disclosed herein comprises a fixed mold, a movable mold, a feed inlet and a cooling water channel, wherein a fixed template of the fixed mold is provided with a guide sleeve, a movable guide pillar is inserted in the guide sleeve, the guide pillar is fixed on a movable template of the movable mold, and the movable mold opens and closes by the guide pillar; the movable mold correspondingly occludes with the fixed mold to form two molding cavities, the two molding cavities are symmetrically arranged along the transverse axis of the movable mold, the molding cavities are two semi-circle arc surfaced cavities formed by respectively extending two connected long sides of a pentagonal thin plate cavity, the axises of the two semi-circle arc surfaced cavities are respectively parallel to the respective extended sides, and the two straight sides extending from the two semi-circle arc surfaced cavities are respectively provided with planar cavities which are vertical to the plane of the pentagonal thin plate cavity. According to the invention, the production process can be simplified, manpower and material resources can be saved, the molding plastic mold disclosed herein is suitable for flow line production of products, the production cost is saved, and the production efficiency of the enterprise is raised.

Description

technical field [0001] The invention relates to a plastic forming mold, in particular to a plastic mold for forming a supporting frame for connecting metal pipes. Background technique [0002] In recent years, with the rapid development and general use of the plastics industry, the strength and precision of engineering plastics have been continuously improved, making the application range of plastic products also expanding, such as household appliances, instruments and meters, construction equipment, automobile industry, Japan, etc. In many fields such as hardware, the proportion of plastic products is increasing rapidly. With the increasing demand for plastic products, higher requirements are placed on the output of plastic molds. However, in terms of existing mold technology, in order to improve production efficiency, it can only be achieved by adding injection molding machines and mold equipment, which will not only increase hardware costs, but also the corresponding equ...

AI Technical Summary

Problems solved by technology

However, based on the existing mold technology, in order to improve production efficiency, it can only be realized by adding injection molding machines and mold equipment, which will not only increase the hardware cost, but also the corresponding equipment maintenance costs and the consumption of electric energy, water energy and other operating costs. And labor costs are not a small expense. Therefore, the huge increase in production costs has seriously limited the development of the plastics industry.

[0003] The existing support frame for connecting metal pipes on the market requires the plastic parts to have high dimensional accuracy and molding interface. The existing plastic molds have low molding efficiency and low yield, which greatly increases production costs and wastes resources.
